(Cl. 194-10) ABSTRACT F THE DISCLSURE A lockoutcircuit for the vend cycle of a multi-selection, coin operated vendingmachine is provided wherein dispensing from a plurality of columns iscontrolled by a vend motor for each column. Each vend motor is arrangedto be energized during the latter portion of its vend cycle through atimer switch. The timer switch is operably connected to preventenergization of a corresponding selector relay if the timer switch isnot in the normal position upon establishment of credit. A cam actuatedlockout switch is electrically connected in circuit and adapted to bedisplaced upon energization of a lockout motor to remove establishedcredit at the proper time and ensure delivery of only one article percredit.

The present invention relates generally to a coin operated vendingmachine for selectively dispensing articles, one at a time, from aplurality of sources and, more particularly, to a novel lockout circuitfor a coin operated vending machine having a multiplicity of stacks orcolumns each of which is adapted to receive a plurality of articles tobe selectively dispensed and a multi-motor arrangement adapted to beenergized for dispensing the articles, one at a time, from one of thestacks in response to a selection by a customer. The lockout circuit ofthe present invention insures delivery of only one article perestablished credit and allows alternate selection of articles when oneselection is stalled.

Coin operated vending machines for selectively dispensing articles, oneat a time, from a plurality of sources are Well known. Such vendingmachines generally comprise a plurality of stacks of articles which maybe vertically arranged in columns in side by side relationship. Upondeposit of a suitable coin, credit is established and adispensing cycleis initiated according to the selection of the customer which causes avend motor to be cycled and a single article to be dispensed from theselected stack.

While various mechanical arrangements are known in the prior art toprevent delivery of more than one article at a time from a stack and toprevent jack-potting of the machine, the lvending industry has not beensuccessful in developing a satisfactory electrical circuit which solvesthe problem of removing established credit at the proper time to insuredelivery of only one article per established credit and which ischaracterized by minimum requirements of .power of operation and minimuminterferences of elements, thereby, allowing a flexibility inconstruction and operation whichreduces the cost of operation andmaintenance.

In known electrical circuit arrangements, there is generally provided atimer switch which is actuated by Ia cam driven by the vend motor. Uponestablishement of proper credit, the vend motor is energized for onecycle and actuates the timer switch to remove the established credit.Although such an arrangement allows delivery of only one article percredit; if the vend motor should stall and thus fail to make a completecycle, the timer switch is not returned to its normal position and theentire vending machine is put out of order, thus removing the machine asa source of revenue and requiring the attendance of maintenancepersonnel. This and other disadvantages of ,be hereinafter describedknown prior art arrangements are overcome by the present invention whichprovides a novel vending cycle lockout circuit which removes establishedcredit 4at the proper time to insure delivery of only one article perestablished credit and which, in the event of a vend motor stall, allowsop eration of the remaining selections.

Accordingly, it is a primary object of the present invention to providea novel vending cycle lockout circuit.

Another object of the present invention is to vprovide a novel vendingcycle lockout circuit which removes established credit at the propertime to insure delivery of only one article per established credit. l

Another object of the present invention is to provide a novel vendingcycle lockout circuit which prevents jackpotting of the machine.

Another object of the present invention is to provide a novel vendingcycle lockout circuit which prevents additional loss of credit on astalled selection.

Another object of the present invention is to provide a novel vendingcycle lockout circuit which will prevent placing the entire vendingmachine Vout of order in the event of a stalled selection and which willallow operation of the vending machine with any number of selectionsstalled so long as there is at least one selection that is not stalled.

The present invention is particularly adapted for use with a coinoperated vending machine having a multiplicity of stacks or columns eachof which may be provided with articles Ofvdiierent characteristics suchas, for example, bottled beverages of dilerent flavors and having amultimotor arrangement for selectively dispensing articles one at a timeaccording to the choice of the customer. To this end, dispensing fromeach column is controlled by a vend motor which is arranged to beenergized during the latter portion of its Vend cycle through a timerswitch. The timer switch is operably connected to prohibit energizationof the corresponding selector relay if the timer switch is not in itsnormal position upon establishment of credit. Lockout means are providedfor removing established credit at the proper time to insure delivery ofonly one bottle per established credit and allow operation of theremaining selections in the event of a stall -in the selected column.Further protective means are provided to prevent jack-potting in theevent of malfunctioning of the lockout means by automaticallydiscontinuing the power to the vend motors to prevent the completion ofthe cycle by the vend motor in the selected column.

Other objects andthe attendant advantages of the present invention wi-llbe apparent from the following description taken in connection with theaccompanying drawing. Although one specific form of the invention isillustrated, it is to be expressly understood-that this drawing is forthe purpose of illustration only and is not intended to represent thefull scope of the invention which is defined by the appended `claimswhich particularly point out and distinctly claim the subject matter ofthe invention.

In the accompanying drawing, FIG. 1 is a schematic diagram of the novelvending cycle lockout circuit of the present invention.

Since the inventive yconcept ofthis invention resides in a new andimproved lockout circuit and is independent of the cabinet in whichit islocated or the means for delivery of the article that is dispensed, Vtheinvention will with reference only `to the schematic of the controlcircuit, its method of operation and control.

Referring to FIG. l, there is illustrated schematically the novelvending cycle lockout circuit of the present invention for a coinoperated vending machine which includes a plurality of stacks or columnsof articles arranged to be selectively dispensed, one at a time,according to the choice of a customer.

in the operating circuit of one stack corresponding to a like componentin other stacks is designated with a like numerical reference characterwhich is followed by an alphabetical character designating theparticular stack with which the component is associated.

- For example, each stack has associated therewith a vend motor 10, atimer switch 11, a pair of sold out switches 12 and 13, a sold outindicator light 14, a selector switch 15 and a selector relay 16. Thosecomponents designated with a numerical character followed by thecharacter A are disposed for operation with respect to stack A to effectselection of an article therefrom according to the choice of a customer.In addition to the components associated with a particular stack, anumber of common control components are provided including a coinoperated vend switch 17, a vend relay 18, a coin reject electromagnet19, a lockout motor 20, a cam operated lockout switch 21, a selectindicator light 22, and a correct change indicator light 23.

Power to the lockout circuit is applied across a pair of supplyconductors 24 and 25 which may be connected to a conventionalalternating current supply source. When the machine is in normal workingorder, credit is estab- ,lished by energization of vend relay V18 uponinsertion of a proper coin into a coin box (not shown) and actuation ofthe coin operated vend switch 17.

Vend switch 17 may be a conventional micro-switch I having a pair offixed contacts 2-6 and 27 and a movable contact arm 28 adapted to bemomentarily displaced from a first position to a second position andreturned to its i'lrst position upon insertion of theproper coin in thevending machine coin box. Movable contact arm 28 is connected to supplyconductor 24 and upon displacement of the arm to its second positioncompletes the energizing circuit to vend relay 18 through contact 27 andconductor 29 connected to one end of the energizing coil 30 of vendrelay 18. The other end of the energizing coil 30 is connected to supplyconductor 25. vConductor 25 also forms a common power Afeed line foreach of the vend motors A-10F sold out indicated lights 14A-141:,selector relays 16A-16F, reject electromagnet 19, select in- Vdicatorlight 22, correct change indicator light 23 and lockout motor 20.

Displacement of movable contact arm 28 also causes power to bemomentarily removed from the starting circuit for the lockout motorwhich is electrically connected to the fixed contact 26 of switch 17.The circuit may be traced from lockout motor 20 through conductor 31,the lower set of contacts, as viewed in the drawing, of an energizedselector relay 16, and conductor 32 connected to fixed contact 26.

Each selector relay 16 includes an energizing coil 33 and upper andlower set of contacts 34 and 35 respectively, as viewed in the drawing.Each set of contacts includes a movable contact arm 36 and 37 forming acommon terminal between Ya pair of corresponding fixed contacts 38, 39and 40, 41. The lower set of contacts 3S is arranged in the startingcircuit fonthe lockout motor 20 as hereinbefore described, while theupper set of contacts 34 is arranged to provide a holding circuit forenergizing coils 33.

To this end, the fixed Contact 40 of each selector relay is connected toconductor 31 by means of a conductor 42, and the movable contact 37 ofeach selector relay is connected in series with the fixed contact 41 ofthe selector relay corresponding to the next succeeding stack throughconductors 43, with the exception of the last stack, wherein the movablecontact 37 is connected to contact 26 of CIK the coin switch 17 throughconductor 32. Each movable contact arm 36 of the upper set 34 issimilarly connected to the xed contact 39 of the selector relaycorresponding to the next succeeding stack through a conductor 44, withthe movable contact arm 36 of the selector relay of the last stack beingconnected to the supply conductor 24 through conductor 45, the lower setof contacts, as viewed in the drawing, of vend relay 18 in its energizedcondition, conductor 46 and the normally closed contacts 26, 28 of coinoperated vend switch 17.

Initial energization of a selector relay is made through thecorresponding selector switch 15, sold out switch 12 and timer switch11. The circuit may be traced from a coil 33 through the correspondingconnecting conductor 47, timer switch 11, conductor 48, sold out switch12, conductor 49, selector switch 15, conductor 68, contacts 36 and 39of relay 16, conductor 45, the lower set of contacts in the energizedposition o f vend relay 18, conductor 46 and coin switch 17 to supplyconductor 24. Energization of coil 33, causes the movable contacts 36and 37 to be displaced from a rst position to a second position incontact with fixed contacts 38 and 40, respectively, to establish theholding circuit for the energizing coils 33 of relay 16 and to estabhshthe starting circuit for v lockout motor 20 through contacts 37, 40.

- energized upon actuation of coin operated vend switch 17,

causing movable contacts 52 and 53 to be displaced downwardly, asviewed, in the drawing. rThis removes from the timing switches 11applied through conductors S8 and 59 leading from fixed contact 56, andapplies power to conductor 45 through xed contact '57 when contact 28returns to its original position.

The normally closed contact 52, 54 of vend relay 18 permit power to beapplied to the coin reject electromagnet 19 when the coil of vend relay18 is deenergized. The circuit may be traced from the electromagnet 19through conductor 60, contacts 52, 54, conductor 61, the normally closedcontacts of sold out switches 13, conductor 62, the normally open, heldclosed contacts of lockout switch 21 and conductor 63 to supplyconductor 24. Energization of vend relay 18 opens the circuit to thecoin reject electromagnet 19 through opening of contacts 52, 54.

Coin reject electromagnet 19 provides a conventional lcoin blockingfunction through operation of its armature (not shown). In its normallyenergized condition, the armature is actuated so as to permit a coin tobe inserted for establishing credit; however, once the coin operatedvend switch 17 is closed and vend relay 18 is energized, the coin rejectelectromagnet 19 is deenergized so as to operatively prevent theinsertion of another coin. Correct change light 23 is connected acrossthe energizing coil of the coin reject electromagnet 19 to provide asuitable indication, when lit, that the vending machine is ready toreceive coins.

As hereinbefore described, the energizing circuit for the coin rejectelectromagnet is established through parallel connected sold outswitches 13. Each sold out switch 13 is disposed at a correspondingstack for monitoring the supplyv and actuation in a conventional mannerfrom a rst to a second position upon depletion of the supply of articlesin that stack. When actuated to its second position switch 13establishes the energizing circuit for a corresponding sold outindicator light 14, but the circuit through the lockout switch 21 is notbroken until all switches 13A-13F are open. A second group of sold outswitches 12 are provided in the energizing circuit of the vend motors tobreak the energizing circuit for a corresponding vend motor in aconventional manner upon depletion of the supply of articles in thestack. Sold out switches12 may be operated independently of sold outswitches 13 or they may be ganged thereto for simultaneous operation.

Each vend motor has associated therewith a corresponding timer` switch11 comprising a movable Contact 64 and a pair of fixed cont-acts 65 and66. Each switch 11 is adapted vvto be actuated between a first position,in which the corresponding vend motor 10 is energized through conductor67, 48, sold out switch 12, conduct-or 49 and an actuated selectorswitch 15, and a second position, after energization of thecorresponding vend motor, to establish a by-pass energizing circuit forthe vend motor through conductor 59. To this end, each timer switch 11may be a microswitch having its movable contact-biased in downwardposition, as viewed in the drawing, and adapted to be released to itssecond position by a timer cam 76 driven from the shaft of acorresponding vend motor.

After energization of the appropriate vend motor, the correspondingtimer cam 76 is driven to allow the corresponding' timer switch to snapto its second position whereupon contacts 64, 65 are closed. Initialenergization of the vend motor is effected through actuation of theselector switch 15 which also establishes the energizing circuit for acorresponding selector relay 16 through contacts 64, 66. Each selectorswitch has one fixed contact 69 serially connected to the movablecontact 70 of the selector switch in the next succeeding stack, the xedcontact 69 of the last selector switch being connected in series withthe select indicator light 22 through conductor 71 to provide a visualindication to the customer that the machine is ready for selection.Movable contact 70 which forms a common terminal for both positions ofthe selector switch is connected at Swich 70A to conductor 68. The otherfixed contact 72 of each selector switch is connected to the movablecontact of a corresponding sold out switch 12. n

Established credit is removed from the circuit upon actuation of the camactuated lockout switch 21 which occurs when lockout motor is energized.In the normal position, lockout switch 21, which may be a conventionalmicroswitch having a movable contact 73 and a pair of fixed contacts 74and 75, provides power to the holding circuit of vend relay 18 throughits contacts 52, 55, sold out switches 13 and conductor 62 connected tothe line 24 through movable contact 73 and xed contact 74. Lockout motor20 revolves a timing cam 77 in a conventional manner, which actuatesswitch 21 to its second position and establishes a secondary energizingcircuit for motor 20 through contacts 73 and 75 and conductor 63connected to supply line 24. Initial energization of lockout motor 20 isestablished as hereinbefore described through conductor 31 uponenergization of one of a selector relay 16.

For convenience, a typical sequence-of-operation of the vending cyclelockout circuit is set forth as follows:

A coin is inserted in the coin box which actuates the coin operated vendswitch 17. Actuation of coin operated vend switch 17 breaks the circuitat contacts 26, 28 and impulses the vend relay 18 through contacts 27,28. Opening of contacts 26, 28 breaks the power source to the lockoutmotor starting circuit in the selector relays 16 and also breaks thepower source to the vend relay credit contacts.

Upon energization of the vend relay 18, the energizing circuit for thecoin reject electromagnet 19 is broken, causing it to rejectfurthercoins. Simultaneously, a holding circuit is established through contacts52, 55 to maintain the vend relay coil 30 energized when the vend switch17 returns to normal. Closure of contacts 53, 57 enables the holdingcircuit for the selector relays.

The machine is now ready for a particular selection by the customerwhich is effected through operation of a selector switch. For example,if the selector switch 15A for the irst stack is actuated, a circuit isestablished for energization of vend motor 10A and also for energizationof selector relay 16A through contacts 64, 66 of timer switch 11A.Selector relay 16A opens contacts 36, 39 'to prevent double vending,while lockout motor 20 is energized through contacts 37, 40. Energizingcurrent to the vend motor 10A is lapplied through the timer switchcontacts 64, 66 upon return of the movable contact arm of the selectorswitch to its original position.

Energization of the vend motor 10A drives the associated timing cam 76Ato cause the timer switch 11A after a suitable interval to snap back tothe second position establishing a by-pass energizing circuit for theVend motor through conductor 59 and breaks the circuit to the selectorrelay energizing coil. This allows the vend motor 10A to continue to runand be carried through the latter part of its cycle through the timerswitch after credit is removed by the lockout switch 21 which isactuated at some time interval after the timer switch has been released,

As hereinbefore described lockout switch 21 establishes the powercircuit to the coin reject electromagnet 19 through its contacts 73, 74and contacts 52, 54 of vend relay 1S, thus allowing the machine toaccept money. When vend relay 18 is energized, the circuit toelectromagnet 19 is broken and lockout switch 21 completes the holdingcircuit of the vend relay established through its contacts 52, 55.

Energization of lockout motor 20 through the selector relay 16A causesthe lockout motor drive cam 77 to actuate lockout switch 21 to itssecond position so as to break the circuit to the holding circuit of thevend relay 18 thereby allowing the ven-d relay to return to its normalstand-by position and remove established credit. This also establishesthe by-pass energizing circuit for vend motor 10A through conductors 58,59 and contacts 64, 65 of timer switch 11A so that the vend motor 10Acontinues to run to complete its cycle and also establishes thesecondary energizing circuit for the lockout motor through contacts 73,75. The vend motor 10A continues to run directly through the timerswitch 11A until the energizing circuit to the vend motor throughcontacts 64, 65 is broken when the timer Iswitch returns to its initialposition which is effected by cam 76.

When vend rel-ay 18 is returned to its normal stand-by position, theenergizing circuit to the holding circuit for selector relay 16A isbroken and the circuit for coin reject electromagnet 19 is enabled;however, the coin reject electromagnet is not energized at this time,because the energizing circuit is open at the lockout switch 21.

The lockout motor continues to run on current directly through thelockout switch contact 73, 75 until the lockout switch 21 is returned toits initial position. Thus, upon release of contact 73 from its secondposition, lockout motor 20 is stopped and power is returned through thesold out switches 13 to the vend relay movable contact 52 an-d rejectelectromagnet 19 is energized. l

In the event of a stall of vend motor 10A, the timer switch 11A does notreturn to the initial stand-by position; however, the remainingselections are unaitected and will operate properly. Since there is noload other than the activation of the lockout switch 21 on the lockoutmotor 20, the lockout motor will always complete its cycle, whileadditional loss of credit on a selection assumed to be stalled isprohibited by breaking the circuit to the corresponding selector relaythrough the open contact of the corresponding timer switch.

The circuit will operate properly with any number of selection stalls,so long as there is at least one selection that is not stalled. Inaddition, to prevent the vend motors from completing their cycle in theevent that the lockout motor fails to activate the lockout switch, theenergizing circuit to the normally closed, held open contacts 64, 65v ofthe timer switch 11 is provided through contacts S3, 56 of the vendrelay. This prevents the vend motors from completing their cycle in theevent that the lockout motor fails to activate the lockout switch andprovides an anti-jackpot feature.

While the lockout circuit of the present invention has been describedwith reference to a particular embodiment, changes in or modificationsto the illustrated embodiment may now be suggested to those skilled inthe art without departing from the present inventive concept.
